Filed:

Apr 30, 2002

Appl. No.:

10/134692

Inventors:

Steven P. Perry - Rochester Hills MI, US
Christophe Sterle - Rochester Hills MI, US

Assignee:

Valeo Climate Control Corp - Auburn Hills

International Classification:

B60H001/00
B60H003/00

US Classification:

165202, 165 42, 165103, 454160

Abstract:

An air flow mixing system for a vehicle air conditioning system having a distribution door to force air from a first air flow to mix with a second air flow of different temperature proximate a merging region in the air conditioning system. In one embodiment, the distribution door has an arcuate passageway or scoop to forcibly route air from the first airflow to the second airflow. In a second embodiment, the distribution door has at least one projecting channel to divide each of the first and second air flows into a plurality of alternating flow paths to promote heat transfer and mixing of the two airflows. In each embodiment, the pivoting distribution door facilitates heat transfer between the airflows resulting in a more even temperate airflow emerging from the merging region.

International Classification:

US Classification:

181279, 181296

Abstract:

A blower for an HVAC system of a motor vehicle. A fan is supplied with airflow by a duct having a bend adjacent to the fan that causes a low-pressure region at a face of the fan. A baffle is located immediately adjacent to the fan face and collocated with at least a portion of the low-pressure region to impede airflow through the face of the fan at that location. The baffle acts to reduce unwanted low frequency noise and improves the mechanical efficiency of the fan. The baffle covers a circular segment of the fan face and may have sound-suppressing features, such as ridges formed on at least one surfaces.
